“…There has been a demonstration of IMDD DCI working at 204 Gbaud and 140 Gbaud VOLUME 10, 2022 over 10 km and 80 km DCIs, respectively [90]. Several implementations are using wideband WDM (which seems to be the future for DCI) and many proposals for using optical amplifiers (using different optical amplifiers to amplify different bands) in such links [84], [91]- [93].…”

We propose and demonstrate a generalized framework for performance limit evaluation and comparison of multihop optical repeated and regenerated links. The model developed is implementation agnostic and applies to multihop optical links of varied forms, including fiber, free space, and underwater links. The framework estimates the best-case performance gains of deploying an all-regenerative link over an all-repeater link for any given implementation. The implementation-independent technique is then illustrated using guided and free-space optical links. An abstract model is developed first with the evolution of signal, noise power, and bit error rate down the link compared and contrasted for both cases. The model is then evaluated using physical parameters for a typical fiber optic intensity-modulated direct detection link, and the obtained all-regenerator link performance advantage is translated to extra reach and lower transmission power requirements. Further, certain approximations are provided to reduce computational complexity and improve the analytical tractability of the procedure, which could be particularly helpful when employed in specialized hardware or for dynamic reconfiguration networks. Finally, the framework's versatility is established by employing it in analyzing an ideal free-space link and comparing amplify and forward links against decode and forward counterparts. Similar results are also reproduced on a commercial optical link simulation suite. Detailed literature on link analysis is provided for fiber, free space, and underwater links, bringing out their similarities. We conclude by elaborating on various current and emerging application domains and certain limitations of the proposed technique.

Performance analysis of WDM MIMO RoFSO links for 5G applications

The soon to be deployed 5G systems are expected to cater an agglomerate of services at profuse data rates wirelessly. Radio over fiber (RoF) networks are the most suitable to implement such systems. In situations where the practical implementation of RoF systems are non-viable, radio over free space optical (RoFSO) links can be employed. The traditional wavelength division multiplexing (WDM) technology can be incorporated to multiply the data rates. However, the link performance may be degraded due to various atmospheric factors. This can be compensated using multiple input multiple output (MIMO) techniques. In this paper, the performance analysis of such a WDM RoFSO link for 5G frequencies is carried out. The work also presents quantitative performance comparison between single input single output (SISO) and MIMO RoFSO links for 5G systems which will be useful for researchers in this area. It is observed that, while WDM provides additional data capacity, it degrades the link performance under adverse weather conditions which can be counterbalanced using MIMO techniques.

High speed networks over long distance with superior transmission efficiency is the need & demand of current and next generation networks. For which, millimetre wave (mm-wave) based many Radio over Fiber (RoF) networks are proposed earlier with several modulation and multiplexing techniques. This paper presents an efficient RoF network comprising of cascaded combination of an Mach Zehnder Modulator (MZM) & a Li-Nb MZM in transmitter alongwith Optical Phase Conjugator (OPC) in the link to improve the extensive bandwidth quality transmission over longer distances. The proposed model reports successful transmission of 8 channel WDM signal with RF signal of 110 GHz over a range of 100 km at 12 Gbps data rate. The model provides an average Bit Error Rate (BER) of 10^(−58) and an average Q-factor of 15.64 when channel spacing is kept at 0.5 nm.
